Pros: 14 of them in 6U space. Dual processor (Intel), hardware raid-1 that pretty much just works, all the time. Basic RH9-friendly (soon to be upgraded to CentOS) /proc information about all kinds of groovy things. Management console *rocks* for remote diagnostics, bios upgrades, remote full lock reboots, and a host of other things. Initial buy-in is highish, but a full bladecenter is pretty reasonable per-machine. Seem to run 2.4.x (old RH9 stuff) decently, I imagine they'll run CentOS fairly well, too. Shared CD-ROM drive for media insertion, that can be switched remotely or by hand. Really clever power redundancy options (see below, too). Cons: Machines use tiny little lam-o 2.5" laptop drives. Big ass PDU that doesn't really have a place to go other than the floor. Huge loud fans to keep that chassis cool. Celeron processors. Strange '2.5G RAM configuration'. Non-individual Gb ethernet connection (*choke*). Ridiculous Gb switching module that you can install into the bladecenter. Pseudo-clever power redundancy options! Why would I want options for power redundancy, for redundancy, all I want is if one dies, the other one has the capacity to run the whole thing! So-so tech support for 'enterprise class' hardware. I also have loads of Dell boxes - a few racks worth. Pros: I like the newer PERC 5/i 1U boxes with a pair of 500GB SATA drives mirrored and 4GB of RAM. I like being able to boot an OMSA/Knoppix CD off a random machine. I like Dell tech support for silver on server hardware. I like Dell's pretty serious support of Linux on PowerEdge hardware. I like the fact that you can talk to people who don't tell you to reformat your computer when you're having hardware issues. I like the big chunky 8-drive backplane on the 5U 2900. I like serial console redirection from the BIOS. I like the extra 'management' ethernet port on the back. I like a pair of dual core Xeon's that appear to be 8 processors in 'top'. I like the completeness of the rackmount hardware, and the general sturdiness and build quality of the 2900/1950 boxes. I even like the el-cheapo 860's. They have people on staff who have helped develop Linux. CentOS 4.4 runs like a *champ* on the new stuff, we'll find out in the next couple of months about all the older stuff. Cons: Expensive. Way too expensive for what you get. Support contracts for 7x24 hardware replacement are ludicrously high for high-end hardware that really shouldn't break in 8-10 years, much less 5 or 3. I think they should just warranty that stuff, and maintain spares locally enough to get it fast, and not charge a fortune for it like it's a 'Best Buy' replacement warranty on a new dvd player. (39.99 on a $45 item). Sales is a PITA to deal with. Takes forever and 3 conference calls to get everything finalized, and then when you want a really simple change to the quote, the prices are all over the map, like every go is a new round of 'Let's Make A Deal'. Lifecycle on Dell Hardware can be measured in milliseconds. They drop a line of server hardware like Paris Hilton changes tapes in a video camera. BROADCOM Gb NIC's! No dual powersupply options randomly on rackmount server hardware. Not even something little and cheesy with two plugs (anymore). Older PERC RAID controller support under modern Linux distributions is a nightmare involving trying to graft a floppy drive into an old ass machine that never had one, or the one it had died, but uses a proprietary interface. /RANT :) Peter -- Peter Serwe <peter at infostreet dot com> http://www.infostreet.com "The only true sports are bullfighting, mountain climbing and auto racing." -Earnest Hemingway "Because everything else requires only one ball." -Unknown "Do you wanna go fast or suck?" -Mike Kojima "There are two things no man will admit he cannot do well: drive and make love." -Sir Stirling Moss
